IMPROVED LUBRICATIN COMPOUND.

Specification forming part of Letters Patent No. 6,028, dated January 16, 1849.

p the following is a full, clear, and exact description of the manner of compounding and using the same.

The lubricator consists in the mixture'of caoutchouc with spirits of turpentine, orother solvent of that gum, carbonate of soda, glue,

common animal or vegetable oil, or other cheap fatty matter, and water, which may be mixediu various proportions. Ihave, however, found the following proportion of the ingredients to answer very wellin the manufacture of the compound, viz: one pound of caoutchouc with sufficient turpentine to dissolveit, four pounds of carbonate of soda, one pound of glue,twenty-four gallons of common oil or grease, and eight gallons of water.

To prepare the compound I first heat the water in any convenient vessel, then dissolve the glue and soda therein, keeping it in agitation by stirring, that the matter may be equally diffused through the water. The oil or grease V is next added, and as soon as it has become well mixed I add the dissolved caoutchouc and continue the stirring until the in gradients are all thoroughly incorporated. The mixture will now be found to have assumed a homogeneous character-in appearance resemblingoilis fit for use, and may be stored away in bottles, barrels, or other convenient vessels.

Some of the materials employed in the abovedescribed composition may be replaced by others possessing similar propertiesf-as, for instance, instead of glue gelatinous matter in other forms may be used; in place otlih e changed in its character by such substitutions or replacements. I do not therefore intend to limit myself to the precise ingredients above enumerated, but contemplate varying both the articles themselves and the proportions in which they are combined,as economy in their cost or adaptation to particular purposes or other circumstances may render expedient.

This compound is as fluid as oil,and is therefore applied as a lubricator in the same manner.

Having thus described the manner in which my anti-attrition is compounded and used, What Iclaiin therein as new, and desire to secure by Letters Patent, is

The combination of ingredients herein described, or of others possessing similar properties and forming an analogous compound, whether the proportions be the same'as herein'set forth or varied to any extent that the same may admit of without changing the peculiar character of the compound as a lubricator.

I testimony whereof I have hereunto set my hand this 1st day of January, A. D. 1849. PATRICK S. DEVLAN.
